Design of a load-balancing architecture for parallel firewalls
Because firewalls can become a potential choke point as network speeds and loads increase, the Navy needs a cost-effective means of increasing data rate through firewalls by placing several machines in parallel and balancing the traffic load among them. Current firewall architectures consisting of …

A theory for the design and analysis of firewalls
Firewalls are the most critical and widely deployed intrusion prevention systems. A firewall is a security guard placed at the point of entry between a private network and the outside Internet such that all incoming and outgoing packets have to pass through it. The function of a firewall is to …

Protecting Vehicles from Remote Attackers with Firewalls and Switched Networks
… an IVN and then create a system of distributed firewalls to enforce it, blocking many remote attacks. Using newer, switched IVN topologies, we can authenticate messages with nearly zero additional overhead and implement our system with minimal changes to each ECU. This places the security …

Firewall information and security visualization : improving the usage and adoption of modern network firewalls by novice users
… their needs. This research focuses on personal firewalls because it is our belief and I will show that personal firewalls are more at risk than those of large corporations. Our hypothesis for this research is that many of the users who install personal firewalls lack the knowledge to properly …

A Federated Architecture for Heuristics Packet Filtering in Cloud Networks
… policies is firewall implementation.</p> <p>Firewalls can be hardware or cloud based. Hardware based firewalls offer the advantage of faster response time, whereas cloud based firewalls are more flexible. In reality the best form of firewall protection is the combination of both hardware and …

Packet filter performance monitor (anti-DDOS algorithm for hybrid topologies)
… an activity monitor to change the states of firewalls based on their performance in a hybrid network. Both firewalls are connected inline. The monitor is mirrored to monitor the firewall states. The monitor reroutes traffic when one of the firewalls become overwhelmed due to a HTTP DDoS …

Firewall-Architekturen für Multimedia-Applikationen
… applications in network environments where firewalls are employed. The provided solutions cover optimizations of existing firewall architectures as well as the development of new mechanisms to implement firewall architectures. Within a global networked environment, security aspects become …

Design, Implementation and Experiments for Moving Target Defense Framework
… techniques such as; redundancy/replications, firewalls, and encryption to prevent attackers from taking control of the system. However, given sufficient time and resources, all these methods can be defeated, especially when dealing with sophisticated attacks from advanced adversaries that …

Design and Implementation of Firewall to Inspect Traffic in Encrypted VPN Tunnels
… in public lines. We have built various kinds of firewalls which can inspect traffic at layer 2, 3, 4 and 7 of OSI model. These firewalls are robust enough and always have high availability build inside in case of failover events. We have various kinds of advanced cyphers which can pack the data …

Adapting the Single-Request/Multiple-Response Message Exchange Pattern to Web Services
… by current in-practice security schemes, such as firewalls and proxy servers. In this thesis, a framework will be proposed to support SRMR and Callback in the context of Web services and the realities of network security. The central component of the proposed solution is a Clearinghouse Web …

Designing security into software
… applications such as antivirus software, firewalls and intrusion detection systems. There is little emphasis on the security in the software itself. Therefore the thesis sets out to investigate if we can develop secure software in the first place. It first starts with a survey of the …

Firewall Policy Optimization and Management
Firewalls enforce a security policy by inspecting packets arriving or departing a network. This is accomplished by sequentially comparing the policy rules with the header of an arriving packet until the first match is found. This process becomes time consuming as policies become larger and more …

Automated Defense Against Worm Propagation.
… few years. Network security elements such as firewalls, IDS, etc have been ineffective against worms. Some worms are so fast that a manual intervention is not possible. This brings in the need for a stronger security architecture which can automatically react to stop worm propagation. The …
